The Security Guards are officers hired by InGen Corporation. Present both at the Dock and the site for Jurassic Park San Diego, they were shocked when Dr. Ian Malcolm sped through the security block and burst inside the facility. Drawing their weapons, they threatened to shoot until it was clear they had other plans for the infant Tyrannosaur. When Malcolm said that if they really wanted to stop then they should shoot them, the guards lowered their weapons.
There are two types of Security Guards, as seen by the different uniforms. Although not all guards are able to be named, there are some which can be identified.
